Hi everyone,
I’m a bass player and while studying harmony I kept wishing there was something more interactive than static diagrams or PDFs.
I wanted a way to explore how scales, intervals, arpeggios, chord progressions and harmonic relationships connect, and actually hear what happens when you tweak things.
So I ended up building a small web app called Notiqs.
Right now it lets you:
* Explore scales in different keys
* Visualize and hear intervals
* Build chords and see their chord tones
* Generate and play chord progressions
* Explore arpeggios
* Use an interactive Circle of Fifths
* Navigate harmonic relationships more visually
* Use an integrated metronome
Everything is interactive and you can instantly hear the results.
It’s completely free, has no ads and doesn’t require signup.
I built this mainly as a learning tool for myself, so I’d genuinely appreciate feedback, especially if something feels theoretically incorrect, unclear, oversimplified, or misleading.
Feature ideas are also very welcome. I’m actively improving it.
Thanks in advance.
